Police hope to speak with four men captured on CCTV as they continue to investigate a sexual assault in Murray Bridge last week.
The men were filmed walking down Joyce Street around 12.30am on January 7, roughly the same time a woman was attacked from behind as she took some rubbish out to a bin in her driveway.
The attacker ran off when a second man called out.
The suspect is described as being a man of average height and build.
At the time of the assault he was wearing a white hoodie with the hood pulled up, possibly over a peaked cap, and dark nylon or parachute pants with a white stripe down each leg.
Senior Sergeant Graham Tomkins, of SA Police's special crimes investigation section, said he believed the four men in the video might be able to help with the investigation.
"Whilst the vision isn't of great quality, you can make out four persons, and the person at the rear of that group is wearing a light-coloured top," he said, noting that did not necessarily mean he was the attacker.
"If you saw those four persons walking around together in Murray Bridge on the evening of Monday, the sixth of January, or the early hours of Tuesday the seventh, or indeed if you're one of those members of that group, we'd appreciate you coming forward," he said.
"I think a light-coloured, white top with black parachute-type tracksuit pants with a white stripe is quite distinctive, and I believe someone in Murray Bridge would know someone who wears that clothing."
He also repeated a request for anyone else with CCTV or dashcam footage taken in the area at the time to provide it: "we have seen cars on the CCTV, so we know there (were) vehicles in the area at the time of the offence".
Senior Sergeant Tomkins said police had so far received one "quite promising" phone call about the case, and hoped the anonymous caller would get in touch again.
Police are providing continued support to the victim, whose children were inside the house at the time.
The special crimes unit, Murray Mallee criminal investigation branch and Forensic Science SA are continuing their investigation.
